Abstract

A surgical delivery instrument for delivering a vascular hole closure device having a hole covering member. The delivery instrument comprises a housing, a plunger and an advancer movable within the housing, the advancer having a first portion and a distal portion hingedly connected to the first portion and forming a casing for supporting the hole covering member. Distal movement of the advancer pivots the casing from an angled position to a more linear position to change the orientation of the covering member from a transverse position to a more aligned position. The plunger is advanceable to advance the covering member into the vessel.

Claims

1. A surgical delivery instrument for delivering into a vessel a vascular hole closure device having a hole covering member, the delivery instrument comprising a first member and a second member and a casing containing the covering member, the first member movable to change an angle of the covering member within the delivery instrument and the second member subsequently movable distally to advance the covering member from the delivery instrument into the vessel, wherein advancement of the first member distally changes the angle of the covering member within the delivery instrument from an initial position to a second position more aligned with a longitudinal axis of the delivery instrument, the casing engageable with an angled inner surface of the delivery instrument to pivot the casing to a more linear position within the delivery instrument.

2. The surgical delivery instrument of claim 1, wherein the first member is movable independently of the second member.

3. The surgical delivery instrument of claim 1, wherein the hole closure device includes first and second flexible members extending proximally from the covering member, the first flexible member having a first engagement member extending therefrom and the second flexible member having a second engagement member extending therefrom, and the delivery instrument further comprises a housing, wherein the housing has first and second engaging portions, the first engaging portion limiting axial movement of the first engagement member and the second engaging portion limiting axial movement of the second engagement member.

4. The surgical delivery instrument of claim 3, wherein the first engagement member is held by the first engaging portion until a predetermined force is applied to the first engagement member and the second engagement member is held by the second engaging portion until a predetermined force is applied to the second engagement member.

5. The surgical delivery instrument of claim 3, wherein proximal movement of the delivery instrument after placement of the covering member advances a first retainer distally from a proximal position further spaced from the covering member toward the covering member.

6. The surgical delivery instrument of claim 5, wherein proximal movement of the delivery instrument after placement of the covering member advances a second retainer distally from a proximal position spaced from the covering member toward the covering member, the first retainer advanced until the first engaging portion is engaged by the first engagement member and the second retainer is advanced until the second engaging portion is engaged by the second engagement member.

7. The delivery instrument of claim 3, wherein the first flexible member is a suture and the second flexible member is a suture, and the delivery instrument further comprises a cutting member positioned therein for automatically severing the sutures.

8. The surgical delivery instrument of claim 1, wherein the second member is advanceable distally within the first member.

9. The surgical delivery instrument of claim 1, further comprising an actuator operatively connected to the first member for advancing the first member.

10. The delivery instrument of claim 9, further comprising a stop to limit movement of the actuator.

11. The delivery instrument of claim 9, further comprising a lockout to lock the actuator in a distal position.

12. The delivery instrument of claim 1, wherein the vascular hole closure device has a first retainer and a second retainer positionable external of the vessel, a first flexible member extending between the covering member and the first retainer, and a second flexible member extending between the covering member and the second retainer, wherein proximal movement of the delivery instrument advances the first retainer and the second retainer toward the covering member.

13. The delivery instrument of claim 1, wherein the first member is lockable in a distal position so the first and second members are together movable proximally to advance first and second retainers of the hole closure device toward the covering member.

14. A surgical delivery instrument for delivering into a vessel a vascular hole closure device having a hole covering member, the delivery instrument comprising a first member and a second member, the first member movable to change the position of the covering member within the delivery instrument and the second member subsequently movable to advance the covering member from the delivery instrument into the vessel, wherein the hole closure device includes first and second flexible members extending proximally from the covering member, the first flexible member having a first engagement member and the second flexible member having a second engagement member, and the delivery instrument further comprises a housing having first and second engaging portions, the first engaging portion limiting movement of the first engagement member and the second engaging portion limiting movement of the second engagement member, wherein the first engagement member is held by the first engaging portion until a predetermined force is applied to the first engagement member and the second engagement member is held by the second engaging portion until a predetermined force is applied to the second engagement member, wherein the first engaging portion comprises a first opening in a first grommet and the second engaging portion comprises a second opening in a second grommet.
